You have that right on the Advanced Nutrients, I have a spreadsheet in my last grow showing the nutrients at 100% cost verses 25% cost and Pennywise got me to use them at 25 % did it the whole flower cycle . At the 100% nutes all those grows I can taste the nutrients (even did the two week flush thing , no still taste nutrients) the 25% no nutrients taste at all!Hey Smokey, I have to agree with you 100% on what you said in your closing about the roots. After 1.5 years of growing in soil & only getting 2.5 - 4.5 oz. per plant I came to the conclusion it's all about growing the roots & not the plant itself so much. I've done everything I can possibly think of to try to increase yield in soil but haven't had a lot of luck. Then it hit me .... this is about growing the roots as big as possible. Because of this I decided to change my whole tent. No more soil in 3 - 5 gal. pots. No more GH Nutes. I ordered a 4 - 5 gallon Auto-Pot system that I'll be using Coco & Perlite in. Switched all my nutes to Advanced Nutrients Coco Formula. Added a 6 gal. Humidifier & will soon be adding Co2 if all my temps & humidity are right once it's all set up & tested for a couple of days. Sure hope this increases yield as it's costing me about $500 - $600 to make these changes. The cost is mainly in the nutes. AN stuff is quite expensive compared to GH products. Sure hope the changes I'm making help.
I bought the CO2 tank $125 amazon and $10 to fill it! The controller and the regulator from amazon also . Before I came to 420 I used the Co2 the first two weeks of flower only . Got that from grow weed easy and followed it . When I got to 420 I did it in veg and was no slowing them down ! You learned as I have bulk roots and what I see light is the main food !
